Note: Arduino is NOT included.OverviewThis AlphaBot2 robot kit is designed to use with an Arduino compatible controller (not included). It features rich common robot functions including line tracking, obstacle avoiding, ultrasonic ranging, infrared remote control, Bluetooth communication, etc.Thanks to the highly integrated modular design, it is fairly easy to assemble by a snap, no soldering, no wiring. After a few minutes spent on hardware assembing, you're almost there, our open source demo codes is ready to help you get started fast.AlphaBot2 FeaturesAlphaBot2 employs a 2-layer structure to provide excellent stability and compatibility.AlphaBot2-Base, the lower base chassis: 5-ch infrared sensor, analog output, combined with PID algorithm, stable line tracking Onboard modules like line tracking, obstacle avoiding, needs no messy wiring TB6612FNG dual H-bridge motor driver, compared with L298P, it's more efficient, more compact, and less heating N20 micro gear motor, with metal gears, low noise, high accuracy Onboard RGB LEDs, true color lighting, pretty cool AlphaBot2-Ar, the upper adapter board for controller: Onboard Arduino interface, into which Arduino controller can be directly plugged 0.96inch 128x64 yellow/blue dual color OLED TLC1543 AD acquisition chip PC8574 I/O expander, avoid I/O shortage Xbee connector, for connecting dual-mode Bluetooth module What's on the AlphaBot2-Base AlphaBot2 control interface: for connecting sorts of controller adapter board Ultrasonic module interface Obstacle avoiding indicators Omni-direction wheel ST188: reflective infrared photoelectric sensor, for obstacle avoiding ITR20001/T: reflective infrared photoelectric sensor, for line tracking Potentiometer for adjusting obstacle avoiding range TB6612FNG dual H-bridge motor driver LM393 voltage comparator N20 micro gear motor reduction rate 1:30, 6V/600RPM Rubber wheels diameter 42mm, width 19mm Power switch Battery holder: supports 14500 batteries WS2812B: true color RGB LEDs Power indicator What's on the AlphaBot2-Ar AlphaBot2 control interface: for connecting AlphaBot2-Base Arduino expansion header: for connecting Arduino shields Arduino interface: for connecting Arduino compatible controller Xbee connector: for connecting dual-mode Bluetooth module, remotely control the robot via Bluetooth IR receiver PC8574: I/O expander, SPI interface Arduino peripheral jumpers TLC1543: 10-bit AD acquisition chip Buzzer 0.96inch OLED SSD1306 driver, 128x64 resolution Joystick Photos AlphaBot2-Ar top view AlphaBot2-Ar bottom view AlphaBot2-Base top view AlphaBot2-Base bottom view AlphaBot2-Ar robot side view AlphaBot2-Ar robot side view AlphaBot2-Ar robot front view AlphaBot2-Ar robot back view AlphaBot2-Ar robot bottom view AlphaBot2-Ar robot bottom view AlphaBot2-Ar robot top view AlphaBot2-Ar robot disassembly Examples AlphaBot2 multi robots line following AlphaBot2-Ar robot line tracking AlphaBot2-Ar robot obstacle avoiding AlphaBot2-Ar robot Bluetooth control Note: photos are FOR REFERENCE ONLY, the other boards/modules/accessories are NOT included in the price.DimensionsDevelopment ResourcesWiki : www.waveshare.com/wiki/AlphaBot2-ArWiki : www.waveshare.com/wiki/UNO_PLUSPackage Content: Weight: 0.282 kg AlphaBot2-Ar Acc Pack Note: this product requires two 14500 batteries to work, which are NOT included and should be purchased separately.
